Industrial Coolants Ammonia Test Strips


Pacific Sentry’s Ammonia Test Strips are a cost-effective, simple, and efficient solution for monitoring and maintaining cooling systems. Regular testing (at least once a month) helps ensure ammonia-based refrigeration systems are functioning properly and not leaking ammonia. This gives your company added insurance against costly losses and downtime. Strips have a large test pad (1/2' x 5/8') for easy viewing. Testing requires no technical skill. They are specifically designed for industrial applications and for use in the harsh solutions of industrial coolants.

Designed to detect ammonia levels ranging from 0.1 ppm to 0.25+ ppm in refrigerant solutions, these strips enable identification of NH3 contamination within secondary fluid loops. Using strips consistently in routine monitoring programs will provide additional protection needed to ensure a safe, efficient, ammonia-based cooling system. Conducting this simple dip-stick test of secondary fluid samples shows visually if there is ammonia leakage from the primary-coolant side of the system.

The test strip is constructed with a state-of-the-art, colored sensor, which changes from orange to green, blue, then purple with increasing levels of ammonia. These ammonia test strips are a cost-effective, simple, and efficient means to check and maintain cooling systems. Regularly testing with the strips ensures ammonia-based refrigeration systems are functioning properly giving your company an added layer of insurance against costly losses and downtime. Early detection of an ammonia leak is critical. Once a leak develops the entire cooling system is compromised and in jeopardy of further piping system erosion and degradation (ammonia is corrosive to non-ferrous metals).

Costly ramifications and risks of catastrophic breakdown can be prevented by early detection. There are also environmental concerns / regulatory consequences for ammonia discharge into the environment. Make the inexpensive investment of regularly testing your cooling system with Pacific Sentry’s industrial strength Ammonia Test Strips to reduce refrigeration system operating costs and risks.

  • Direct measurement of NH3
  • Easy to use- simply immerse test strip in coolant solution then compare sensor color response to the NH3 color chart
    • No liquids to measure
  • Large test pad for easy readout - with a big pad measuring 1/2' x 5/8', these larger-than-industry test strips allow for easier color comparison
  • High sensitivity - visible color change at 0.1 ppm
  • Readout range incremented - 0.00, 0.1, 0.25, >0.25 ppm
  • Robust - specifically designed for industrial strength coolants
  • No reagents - just immerse in coolant solution and observe color change
  • 4 year shelf life - saves you money
  • No hazardous waste - avoid hazardous waste disposal costs

DO NOT touch the pad at the end of the strip. Oils and residues from the hands and skin can contaminate the sensor and interfere with its response.

Reseal package between uses and when storing. Store at room temperature. Be aware some cleaning solutions, paints, epoxies, and cigarette smoke, contain ammonia or ammonia-related compounds.  Exposing the test strips to such vapors or fumes should be avoided because, as expected, it will result in a color response by the sensor.  

NH3 outgases from test samples over time. It is therefore wise practice to conduct testing soon after obtaining the sample solution.  (If outgassing occurs, samples testing conducted at different times over extended periods can yield variable test results.)
